Edimax GS-5008PL firmware version 1.00.54 and prior use cleartext HTTP for the web management interface without implementing TLS or SSL encryption. Attackers on the same network can intercept management traffic to capture administrator credentials and sensitive configuration data.

Edimax GS-5008PL firmware version 1.00.54 and prior contain a cross-site request forgery vulnerability that allows remote attackers to perform unauthorized administrative actions by inducing logged-in administrators to visit malicious pages. Attackers can exploit the lack of anti-CSRF tokens and request validation to change passwords, upload firmware, reboot the device, perform factory resets, or modify network configurations.

Edimax GS-5008PL firmware version 1.00.54 and prior contain a stored cross-site scripting vulnerability in the systemnameset.cgi script that allows attackers to inject arbitrary script code by manipulating the sysName parameter. Attackers can send a crafted POST request with malicious script payload that executes when management pages including systemdata.js are viewed by administrators.

Edimax GS-5008PL firmware version 1.00.54 and prior contain an insecure credential storage vulnerability that allows attackers to obtain administrator credentials by accessing configuration backup files. Attackers can download the config.bin file through fupload.cgi to extract plaintext username and password fields for unauthorized administrative access.

Edimax GS-5008PL firmware versions 1.00.54 and prior contain an authentication bypass vulnerability that allows unauthenticated attackers to access the management interface. Attackers can exploit the global authentication flag mechanism to gain administrative access without credentials after any user authenticates, enabling unauthorized password changes, firmware uploads, and configuration modifications.
